84 -- Considering the figure showing the orientation of molecules in an electric field, which statement is incorrect?
[Figure: A battery connected to two plates, with molecules labeled E, D, and A oriented between the plates in an electric field X.]
  1. [(1)] D, A, and E can respectively be molecules HI, $\mathrm{SiH_4}$, and $\mathrm{H_2S}$.
  2. [(2)] If molecule E is $\mathrm{H_2O}$, surface X has a negative electric charge and the dipole moment of molecule D is zero.
  3. [(3)] If molecule E is $\mathrm{SO_2}$, the partial charge of the lateral atoms, Y, is opposite to the electric charge of surface Y.
  4. [(4)] If molecule A is HCl, the partial charge of the lateral atoms of molecule D can be the same as the partial charge of the Cl atom in molecule A.
